Median
Median
[
list
]
gives the median of the elements in
list
.
Median
[
dist
]
gives the median of the symbolic distribution
dist
.
MORE INFORMATION
Median
[
list
]
gives the center element in the sorted version of
list
, or the average of the two center elements if
list
is of even length.
Median
[{{
x
1
,
y
1
,
...
}, {
x
2
,
y
2
,
...
},
...
}]
gives
{Median[{
x
1
,
x
2
,
...
}], Median[{
y
1
,
y
2
,
...
}]}
.
Median
works with
SparseArray
objects.

Basic Examples
(3)
Find the middle value in the list:
Average the two middle values:
Median
of a symbolic distribution:
Find the middle value in the list:
In[1]:=
Out[1]=
Average the two middle values:

Out[1]=
Scope
(4)
Median
works with any real numeric quantities:
Median
finds medians of elements in each column:
Obtain results at any precision:
Compute results for a large vector or matrix:
Generalizations & Extensions
(1)
Compute results for a
SparseArray
:
Applications
(2)
Obtain a robust estimate of location when outliers are present:
Extreme values have a large influence on the
Mean
:
Medians of random reals approach a Gaussian distribution:
Theoretical curve:
Properties & Relations
(4)
Median
is equivalent to a parametrized
Quantile
:
For nearly symmetric samples,
Median
and
Mean
are nearly the same:
The
Median
of absolute deviations from the
Median
is
MedianDeviation
:
MovingMedian
is a sequence of medians:
Possible Issues
(1)
Median
requires numeric values:
